Thanks for including so many internal and tear-down photos. Flipping through is very helpful towards reassembly of the parts pile I inherited. You've also boosted my confidence, because if you can successfully restore that car my project is very simple in comparison.

The BLACK stuff is POR-patch. Used as a weld seam sealer. The GREEN stuff coming out of the seat support hat channel is Eastwood interior channel spray. It comes with a long nozzle to reach inside things.

I installed the engine into this car a few years back, the owner who did most of the hard work really made a top notch car. The front trunk work was well though out and very high grade industrial style design. Very purpose built. I remember driving the car for the first time, the rear end dug into the ground and threw the car forward, very fast car.
